Question

The line l cuts the y-axis at (0, 5). l also passes through the point (2, 1). find the equation of the line which is parallel to l and which passes through the point (3, 0).

Answer 1

Answer:
`y=-2x+6`

Explanation:

The slope of line l is

`(5-1)/(0-2)=-2`

Since parallel lines have the same slope, the slope of the line we need to find is -2.

Substituting into point-slope form,

`y=-2(x-3)\\\\y=-2x+6`
